10/6/2018 Colors of tide XTide graphs changed to emphasize that they were upgraded. See next note. Comments welcome. 10/4/2018 I have fixed XTide and updated the harmonic files. There were some name changes so you might have to click EDIT to find the new station name. |

GMZ300 Synopsis For High Island To The Matagorda Ship Channel Out 60 Nautical Miles Including Galveston And Matagorda Bays 916 Am Cdt Tue May 21 2019
Synopsis for high island to matagorda ship channel out 60 nm.. Hazardous marine conditions are expected today but should gradually decrease. Wind gusts to or above gale force are expected through mid morning before very slowly diminishing. We have started to see that trend of decreasing winds so the gale warning has been allowed to expire. A small craft advisory is in effect for most of the day. Moderate to occasionally strong onshore flow and elevated seas are expected for the next several days.

Area Discussion for - Houston/Galveston, TX
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus64 khgx 211738 afdhgx area forecast discussion national weather service houston galveston tx 1238 pm cdt Tue may 21 2019 Aviation [18z TAF issuance] Visible satellite imagery and radar data show a line of showers with maybe some embedded tsra but tsra have yet to really develop. There have been some cell sin the line that have become more developed than others, but in large, capping is limiting vertical development. It's still possible that could change such that an isolated storm could form as the convective line moves more towards houston. Model trends suggest the capping will limit thunderstorm development especially south of kiah. Kiah northward we will keep a mention of vcts this afternoon for the potential of an isolated storm, but overall think we will mainly have showers. Threat for tsra should come to an end later this evening as most activity slides NE with the main upper level trough axis over the plains. Southerly winds should decrease some this afternoon but enough of a southerly breeze should persist overnight to keep fog from forming. MVFR ceilings should develop again with maybe some pockets of ifr. For now tafs keep MVFR ceilings with winds expected overnight. Tomorrow should see improvement in ceilings after 15z going into the afternoon. Overpeck Prev discussion issued 1044 am cdt Tue may 21 2019 Discussion A couple lines of weak precipitation moving into the cwfa from the w NW this morning seem to be holding together as they move further e with time. The initial line (outflow?) should weaken as it moves through the area... But will have to keep an eye on the second line as near-term models morning soundings are indicating a decent pot- ential for strong thunderstorms this afternoon. Locations north of i-10 should see the highest pops with much lower numbers closer to the coast (where the cap seems to be stronger). Current grids seem to be on track, so not planning on a lot (if any) changes with the update. 41 |

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program. |
